Machining details of formwork
1. The number shall be uniform, and the mold core shall be numbered. The number shall be consistent with the number on the mold shelf and the direction shall be consistent.
2.A/B plate processing (i.e. dynamic and fixed mould frame processing)
A.A /B plate machining shall ensure that the parallelism and perpendicularity of the mold frame shall be 0.02mm.
B. milling machine processing: screw holes, water holes, pin holes, nose holes, chamfering
C: locksmith processing: tapping and trimming.
3. Panel processing: milling machine machining and boring machine mouth hole or processing material mouth hole.
4. Top pin fixed plate processing: milling machine processing: top pin plate and
The B plate is connected with the return pin, the B plate is upward, and the top pin hole is drilled from top to bottom.
Thimble countersink needs to turn the thimble plate to the bottom upward, correction, first rough machining with the drill, and then fine machining with the milling cutter in place, chamfer.
5. Floor processing: milling machine processing: marking, correction, boring, chamfering.
(note: for some moulds that require a strong top, a strong top mechanism shall be added, such as adding a screw hole to the thimble plate)
Mold core machining details
1. Rough machining of six edges: machining on the milling machine to ensure vertical and parallel degree, and leave grinding allowance
The 1.2 mm
2. Rough grinding: for large water milling, grind the large surface first, and clip the small surface with the batch to ensure the perpendicularity and smoothness at 0.05mm, and leave a margin of 0.6-0.8mm on both sides
3. Milling machine processing: firstly calibrate the milling machine head within 0.02mm, adjust the pressing workpiece, first process the screw hole, pin hole, thread hole, insert pin countersink hole, machine or material tip hole, split taper hole chamfer, then do the water hole and mill R Angle.
4. Locksmith processing: tapping teeth, typing code
5.CNC rough machining: leave a margin
6. External heating zone hrc48-52
7. Fine grinding;The big water mill is processed to 0.04mm less than the mold frame, and the parallelism and verticality shall be within 0.02mm
8. CNC machining
edm
10. Linear cutting (slow-moving wire) precision: plus or minus 0.005.
11. Save mold, ensure smooth finish and control the size of the mold cavity.
12. Process the gate and vent. Generally, open the gate 0.3-0.5mm, vent 0.06-0.1mm, open the gate 0.5-1.2mm for aluminum alloy, vent 0.1-0.2, and vent 0.01-0.02 for plastic, as wide as possible and thin as possible.
Processing technology of sliding block
1. First, milling machine rough machining six sides,
2. Grinding the six sides to the size requirement;
3. Rough machining platform for milling machine,
4. The mounting table is ground to the size requirement and matched with the horizontal sliding of the formwork.
5. The milling machine can process the inclined surface to ensure that the slope is consistent with the compaction block, and the flying modulus is left.
6. Drill water and oblique guide holes, the holes of inclined guide column are 1 mm larger than the guide column, and the Angle of inclined guide column should be 2 degrees less than that of the inclined plane of the sliding block.The slant guide hole can also be reprocessed with the die frame after the die has been completed and closed, depending on different conditions.
